PURPOSE: A sliding window frame is provided to improve the air-tightness thereof since a space between a window frame and a lower fixed frame is minimized. CONSTITUTION: A sliding window frame comprises upper and lower fixed frames(11,13), left and right fixed frames, and an anti-separation auxiliary bar(20). The upper and lower fixed frames are fixed to the wall of the building with being horizontally separated from each other. The left and right fixed frames are vertically formed separated from each other on the left and right sides of the upper and lower fixed frames and are fixed to a building wall. The anti-separation auxiliary bar is fixed to the lower part of a rail(110) of the upper fixed frame. The anti-separation auxiliary bar prevents the window frame from becoming separated. The window frame is formed between the upper and lower fixed frames and the left and right fixed frames to move horizontally. |
